BACKGROUND: Glycolysis breakdowns glucose into essential building blocks and ATP/NAD(P)H for the cell, occupying a central role in its growth and bio-production. Among glycolytic pathways, the Entner Doudoroff pathway (EDP) is a more thermodynamically favorable pathway with fewer enzymatic steps than either the Embden-Meyerhof-Parnas pathway (EMPP) or the oxidative pentose phosphate pathway (OPPP). However, Escherichia coli do not use their native EDP for glucose metabolism. RESULTS: Overexpression of edd and eda in E...

To enhance extraction of strongly bound metals from oxide minerals and organic matter, this study examined the sequential use of reductants, oxidants, alkaline solvents and organic acids followed by a biodegradable chelating agent (EDDS, [S,S]-ethylene-diamine-disuccinic-acid) in a two-stage soil washing. The soil was contaminated by Cu, Zn, and Pb at an e-waste recycling site in Qingyuan city, China. In addition to extraction efficiency, this study also examined the fate of residual metals (e.g., leachability, bioaccessibility, and distribution) and the soil quality parameters (i...

The length of stay for moderately preterm infants has progressively become shorter in the UK in recent years but staff still commonly inform parents that their baby will go home around their estimated date of delivery (EDD). Parents need as much notice as possible to prepare for the discharge of their baby, and to gain the necessary skills and knowledge to care for their infant safely. We report the use of routinely collected neonatal data to develop and implement a simple centile chart for date of discharge from hospital, which allows staff and parents to predict the likely discharge date more accurately for preterm infants, most of whom now go home more than 3 weeks before their EDD...

INTRODUCTION: Gestational age is estimated by ultrasound using fetal size as a proxy for age, although variance in early growth affects reliability. The aim of this study was to identify characteristics associated with discrepancies between last menstrual period-based (EDD-LMP) and ultrasound-based (EDD-US) estimated delivery dates. MATERIAL AND METHODS: We identified all singleton births (n=1,201,679) recorded in the Swedish Medical Birth Register 1995-2010, to assess the association between maternal/fetal characteristics and large negative and large positive discrepancies (EDD-LMP earlier than EDD-US and10(th) percentile in the discrepancy distribution vs...

Renal Rhbg is localized to the basolateral membrane of intercalated cells and is involved in NH3/NH4+ transport. The structure of Rhbg is not yet resolved however a high-resolution crystal structure of AmtB, a bacterial homologue of Rh, has been determined. We aligned the sequence of Rhbg to AmtB and identified important sites of Rhbg that may affect transport. Our analysis positioned three conserved amino acids, Histidine-183 (H183), Histidine-342 (H342) and Tryptophan-230 (W230), within the hydrophobic pore where they presumably serve to control NH3 transport...

BACKGROUND: Eccrine duct dilation (EDD) and syringoma-like sweat duct proliferation have been described as reactive changes occurring in a variety of skin conditions. However, extensive evaluation of EDD in scalp biopsies performed for alopecia has not been performed. METHODS: We retrospectively examined 129 cases of cicatricial alopecia (lichen planopilaris, central centrifugal cicatricial alopecia, and discoid lupus erythematosus) and 130 cases of noncicatricial alopecias (androgenetic alopecia, telogen effluvium, and alopecia areata) for the presence of EDD...

Protein fold classification plays an important role in both protein functional analysis and drug design. The number of proteins in PDB is very large, but only a very small part is categorized and stored in the SCOPe database. Therefore, it is necessary to develop an efficient method for protein fold classification. In recent years, a variety of classification methods have been used in many protein fold classification studies. In this study, we propose a novel classification method called proFold. We import protein tertiary structure in the period of feature extraction and employ a novel ensemble strategy in the period of classifier training...

Inhibition of mammalian target of rapamycin, mTOR, extends lifespan and reduces age-related disease. It is not known what role mTOR plays in the arterial aging phenotype or if mTOR inhibition by dietary rapamycin ameliorates age-related arterial dysfunction. To explore this, young (3.8 ± 0.6 months) and old (30.3 ± 0.2 months) male B6D2F1 mice were fed a rapamycin supplemented or control diet for 6-8 weeks. Although there were few other notable changes in animal characteristics after rapamycin treatment, we found that glucose tolerance improved in old mice, but was impaired in young mice, after rapamycin supplementation (both P < 0...

Orthologs search identified that the Vibrio cholerae gluconate (Gnt) utilization system minimally consisted of the Entner-Doudoroff (ED) pathway (edd and eda) and three other genes namely gntU, gntK and gntR This system appeared unique, by genomic organization of component genes into two operons transcribed in opposite directions. In silico analysis indicated GntU as inner-membrane protein functioning for transport and GntK as kinase with cytosolic localization which generates Gnt6P, then metabolized through the ED pathway...

BACKGROUND: B-type natriuretic peptide (BNP) levels are elevated in children with congenital heart disease involving a left-to-right shunt (LRS) and are also raised in dilated cardiomyopathy (DCM). As far as we know, there are few reports in the literature comparing the change of the NT-proBNP in LRS and DCM especially in the pediatric age group. OBJECTIVES: The aim of the study was to compare the changes of the NT-proBNP in pediatric patients with LRS and DCM. Correlation between the levels of NT-proBNP and the echocardiographic parameters in both groups was determined...

The application of UV-Fenton processes with two chelating agents, nitrilotriacetic acid (NTA) and [S,S]-ethylenediamine-N,N'-disuccinic acid ([S,S]-EDDS), for the treatment of oil sands process-affected water (OSPW) at natural pH was investigated. The half-wave potentials of Fe(III/II)NTA and Fe(III/II)EDDS and the UV photolysis of the complexes in Milli-Q water and OSPW were compared. Under optimum conditions, UV-NTA-Fenton exhibited higher efficiency than UV-EDDS-Fenton in the removal of acid extractable organic fraction (66...

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) causes significant cardiovascular morbidity and mortality. Current consensus guidelines reflect the neutral results from randomised controlled trials (RCTs). Adequate trial reporting is a fundamental requirement before concluding on RCT intervention efficacy and is necessary for accurate meta-analysis and to provide insight into future trial design. The Consolidated Standards of Reporting Trials (CONSORT) 2010 statement provides a framework for complete trial reporting...

Ice nucleation is of fundamental significance in many areas, including atmospheric science, food technology, and cryobiology. In this study, we investigated the ice-nucleation characteristics of picoliter-sized drops consisting of different D2O and H2O mixtures with and without the ice-nucleating bacteria Pseudomonas syringae. We also studied the effects of commonly used cryoprotectants such as ethylene glycol, propylene glycol, and trehalose on the nucleation characteristics of D2O and H2O mixtures. The results show that the median freezing temperature of the suspension containing 1 mg/mL of a lyophilized preparation of P...

Pneumocandins are lipohexapeptides of the echinocandin family that inhibit fungal 1,3-β-glucan synthase. Most of the pathway steps have been identified previously. However, the lipoinitiation reaction has not yet been experimentally verified. Herein, we investigate the lipoinitiation step of pneumocandin biosynthesis in Glarea lozoyensis and demonstrate that the gene product, GLligase, catalyzes this step. Disruption of GLHYD, a gene encoding a putative type II thioesterase and sitting upstream of the pneumocandin acyl side chain synthase gene, GLPKS4, revealed that GLHYD was necessary for optimal function of GLPKS4 and to attain normal levels of pneumocandin production...
